At prestnt, the resisting mixture filter with high gradient is used to avoid the frequency from folding-effect mixed in engineering vibration measurement. In this paper, the factors of influencing filtering gradient are discussed and the reasonable filtering gradients in measurement of various parameters are put forward.
